I bought this frame adapter to enable my wife's mountain bike to fit on a Thule 910XT Passage 2 bike strap rack. I did not see specifications advertised to indicate the range of bike sizes (measuring from seat post to handle bar stem), but assumed it would work on my wife's bike (it is standard size for woman's bike--with distance from stem to post of 22 inches). Surprise!! The smallest size for this frame adadpter is 23.5 inches in order to be able to tighten it on these two attachment points. I could attach it very loosely, which was not good enough to keep the bike securely on the bike rack. I was amazed and disappointed that Thule did not design the frame adaptor for its intended customers (women's and kids bikes are generally not large).

I'm going to contact EMS to see if the frame adaptor can be returned or exchanged with one that will fit correctly.

Bottom LineNo, I would not recommend this to a friend

Merchant response: Thank you for your review! We'll certainly work with Thule to find the adapter you need! Please give us a call!

I own 3 of these frame adapters and I love them. I use to install my Y-frame mountain bikes on the roof of my SUV but with a Honda Pilot, it's quite high. I've purchased a Thule Revolver and can now use the adapter for both mountain bikes and my son's mountain bike. It adds an additional step to install the bikes on the rack but much more practical then removing the front wheel.
